A jury is now deliberating the fate of Const. James Forcillo, the Toronto police officer charged in the 2013 shooting death of 18-year-old Sammy Yatim.

Here are some key dates worth knowing in relation to the case:

July 27, 2013 — Forcillo shoots nine bullets at Yatim after a 50-second standoff in which he repeatedly yells at the teenager to drop a small knife the youth was holding. Yatim dies on the empty streetcar. The Special Investigations Unit — Ontario's police watchdog — begins its investigation of the incident.

July 29, 2013 — Forcillo is suspended with pay from the police force. Toronto's police chief says the force will do everything it can to answer all the questions surrounding Yatim's "tragic" death. Hundreds of people, including members of Yatim's family, take to the streets of downtown Toronto to protest the killing.

July 30, 2013 — Forcillo is publicly identified as the officer who killed Yatim.

Aug. 19, 2013 — Forcillo is charged with second-degree murder in Yatim's death.

Aug. 20, 2013 — Forcillo is released on $510,000 bail.

Ontario's police watchdog began investigating Yatim's death almost immediately following the fatal streetcar encounter.

June 17, 2014 — Forcillo is committed to stand trial on his second-degree murder charge after the conclusion of a preliminary inquiry.

July 24, 2014 — Former Supreme Court of Canada justice Frank Iacobucci releases his report on the use of lethal force by Toronto police, which was sparked by Yatim's death. Among 84 recommendations, the review suggests that expanding police use of Tasers, equipping officers with body-worn cameras and educating them on mental-health issues could help prevent deadly use of force when dealing with those in crisis.

July 30, 2014 — Forcillo faces an additional charge of attempted murder in relation to Yatim's death.

Sept. 30, 2015 — Forcillo pleads not guilty to second-degree murder and attempted murder in Yatim's death.

Oct. 20, 2015 — Opening statements are delivered at Forcillo's trial in Toronto. Crown lawyers argue Forcillo's actions during his confrontation with Yatim weren't necessary or reasonable. His lawyer contends the officer's actions were justified and carried out in self-defence.

Nov. 25, 2015 — Forcillo takes the stand in his own defence, saying he never intended to kill anyone on the night he confronted Yatim.
